Brandling Safari: LAN safari-zone creature catching on the HD-2D engine

- Authoritative 30 Hz server (ENet, SQLite): accounts, characters, wild AI, tall grass /
  water / wandering spawns, fishing, captures, follower chains, clock + weather, LAN beacon
- Client: title / join / character creator / play screens, prediction + reconciliation,
  interpolated players and parties, HD-2D UI (dialogue with Professor Henry, HUD, collection)
- Shared deterministic zone generator, movement, protocol, roster, appearance
- Paper-doll character art pipeline (PixelLab base walk + per-item animation edits)
- Brandling roster from the company list (logo colors, jev types), Blender safari props
- Headless test bot
